The OSIRIS-REx asteroid sample-return mission is currently orbiting primitive near-Earth asteroid (101955) Bennu. Thousands of images are being acquired by the MapCam instrument onboard the spacecraft. In this work, we present preliminary results of a spectral clustering analysis applied to these color images.

The endohedral fullerene [Li@C60]+PF6− was characterized by differential scanning calorimetry (DSC), by electronic absorption spectroscopy in the spectral range from 195 to 800 nm and by FT-IR and far-infrared spectroscopy. [Li@C60]+PF6− shows a sharp melting point with the onset at 86 °C and peak at 90 °C and melting enthalpy of 9.5 kJ/mol. The

The distribution of galaxies on a colour-magnitude diagram reveals a bimodality, featuring a passively evolving red sequence and a star-forming blue cloud. The region between these two, the green valley (GV), represents a fundamental transition where quenching processes operate. We exploit an alternative definition of the GV using the 4000 Å break

Accurate line lists are crucial for correctly modelling a variety of astrophysical phenomena, including stellar photospheres and the atmospheres of extrasolar planets. This paper presents a new line database TOTO for the main isotopologues of titanium oxide (TiO): ^{46}Ti^{16}O, ^{47}Ti^{16}O, ^{48}Ti^{16}O, ^{49}Ti^{16}O, and ^{50}Ti^{16}O. The ^

The "European CMB Coordinator" group has a roadmap consisting of three axes: One is to build and deploy a 5m reflecting telescope at the South Pole; a second is to build and deploy 0.5m refracting telescopes in the Atacama Desert in Chile; and a third is to deploy low-frequency telescopes aimed at characterizing the sky in the 5-40 GHz range.

We outline a number of science advantages for adding a K or Ks filter (lambda_c 2.15 microns) and propose to extend the wavelength coverage for WFIRST into the K-band, where the gains of going to space are much more pronounced than at shorter wavelengths.
